IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 3,6414, dated July 1,1844.

declare that the following is a full, clear, and

exact description thereof, reference being had to the accompanyingdrawings. which form a part of' this specification, in which- Figure lis a side elevation of the landside ofthe plow; Fig. 2, same side withcutter detached; Fig. plan ot' bottom of the plow with the shareremoved.

The nature ot' my invention consists in connecting the cutter firmly to`the plow, and in such a manner as to be easily detached, the cutter.being made so as to be easily and cheaply renewed when worn out, andalso in the connection of the landside with the mold-board.

The mold-board ot' my 'plow is similar to many in Vcommon use. The shetha, which is cast with it, has a rabbet or recess, b, on its front edgeon the landside, as shown in Fig. 2. The outline of this rabbet runsdown from the beam, nearly perpendicular from the beam, alittle'inclining back about one-third thedistance to the share. It theninclines forward till it reaches a point a little below the landside, ata', which has a semicircular rece ss backward, and then extends forwardand down to the share in a curved line. All this is clearly shown inFigs. l and 2. In the beam there is a mortise on the under side,directly over this recess, which is designated by a dotted line, c. Thismortise extends about half through the beam, and adjoining it behind.The mortise for the sheth is eut through the beam in the usual way forthe staple on the sheth, which projects through the beam and is keyed onthe top.

The cutter d is a thin at casting, the back edge of which is formed to tthe recess in the sheth. The front edge is curved in a line parallel tothe front edge of the mold-board, and atthe lower front corner, d', isout o nearly perpendicular, va little projecting at its lower corner.This curved front edge of the cutter is charnfered oft from themold-board to a sharp edge on the landside. The upper end of it entersthe mortise c in the beam, and a bolt, e, passes through thesemicircular projection near the bottom, and is fastened with a nnt,f,inside. (Shown at Fig. 3.)

The hare g is a at plate of triangular form,

the edge View ot' which is seen in Fig. l. lt extends through to themold-board, beyond which itprojl-ctsinacutting-edge. Itis bolted to itby bolts passingthrough holes in the moldboax-d at h h, Fig.3. Themold-boird and landside are recessed a little to form a bed for it, andwhen put together they are all flush below from the straight front lowercorner, d', ot the cutter, where itjoins the curve. iilled with atriangular pin, t', which is joined to the share and laps up over it,thus confining and protecting and fastening the front corner of thecutter.

The mold-board has a short projection cast on it in a line with thelamlside, extending back from the sheth, which t'orms a short or falselandside. This is represented at lc, Fig. 3, and by dotted lilies inFig. l. To the outside of this false landside a landsiilc, m, isfastened by means ot a loop, n, which projects through from the landsidem, and a wooden key, o, is driven in and unites them, at the same timeallowing a little elasticity in the con nection.

The advantages of the above-described construction of cutter and mannerot' attaching it are that a thin plate can be used that is cheaplyrenewed, andwhich is firmly sustained by the mold-board, sheth, andbeam, the edge only projecting beyond the front of the mold-board.

What I claim as my invention, and desire to secure by Letters Patent,is-

lhc cutter' d, constructed and arranged as herein-described, incombination with thesheth and beam, as above set forth.
